Cost vs Value

I always tell my clients that a kitchen or bathroom remodel is an excellent investment in their homes. But today's email brought a question from Kathi, a long time client...How much of the investment in a central air conditioning system would they expect to recoup when the property is sold someday?
Central air falls in the category of optional (at least in our climate) items that attract buyers and will make the home more appealing. These are the things that make the house sell more quickly and for top dollar, but don't necessarily return all of the cost to the sellers.
Other examples are ultra-expensive materials used in remodeling, and top grade hardwood floors,appliances, carpeting and window coverings.
By all means, buy yourselves these luxuries, especially if you expect to be in the house for many years, but be aware that the $20,000 Wolf range won't pay for itself when you sell a mid-priced rancher.
